SUBORDER HETEROSTRACI Meaning and Definition

1. Suborder Heterostraci is a taxonomical subdivision within the class Agnatha, which refers to a group of extinct armored jawless fish. The suborder Heterostraci includes various species that lived during the Silurian and Devonian periods, approximately 420 to 360 million years ago.

   These fish had a distinctive appearance, with a broad, flattened body covered in a protective armor made up of numerous bony plates known as osteoderms. The plates were arranged in overlapping rows and often had distinctive patterns. The head of Heterostraci fish was also armored, featuring a ventrally-located mouth and two eyes.

   One of the defining characteristics of the Heterostraci suborder is the presence of a heterocercal tail, which means that the upper and lower lobes of the tail are of unequal length. This tail structure improved stability and maneuverability in water.

   Heterostraci fish were predominantly bottom-dwellers, occupying various freshwater environments, including streams, rivers, and lakes. They likely used a suction-feeding method to capture their prey, which may have included small invertebrates, algae, and detritus.

   The fossils of Heterostraci fish are valuable for understanding the evolutionary history of jawless fishes and the development of early vertebrate armor. These ancient fish play an important role in deciphering the evolutionary transitions that led to the emergence of more advanced vertebrates, including the jawed fishes and ultimately the tetrapod lineage.

The term "suborder" is used to classify a group of organisms that are below the rank of order but above the rank of family.

2. Heterostraci: The term "Heterostraci" refers to a subclass of prehistoric armored jawless fish that lived during the Devonian period. It is derived from the Greek words "heteros", meaning "different" or "other", and "strakes", meaning "thin plates" or "scales".
